此功能添加涉及到以下文件：
dede/catalog_add.php
dede/catalog_edit.php
dede/templets/catalog_add.htm
dede/templets/catalog_edit.htm
include/taglib/channel.lib.php
此升级修改方法，在V5.7，V5.7sp1 测试通过，其他版本未测试，原理基本相同，请大家自行测试是否可行。
首先给 栏目表(`dede_arctype`)增加一个字段typeimg
alter table `dede_arctype` add `typeimg` varchar(200) NOT NULL default ;
修改catalog_add.php文件
打开dede/catalog_add.php
查找$queryTemplate = “insert into `dede_arctype`
将
(reid,topid,sortrank,typename,typedir,
替换为：
(reid,topid,sortrank,typename,typedir,typeimg,
将
(‘~reid~’,’~topid~’,’~rank~’,’~typename~’,’~typedir~’,
替换为：
(‘~reid~’,’~topid~’,’~rank~’,’~typename~’,’~typedir~’,’~typeimg~’,
查找$in_query = “INSERT INTO `dede_arctype`
将
(reid,topid,sortrank,typename,typedir,
替换为：
(reid,topid,sortrank,typename,typedir,typeimg,
将
(‘$reid’,’$topid’,’$sortrank’,’$typename’,’$typedir’,
替换为：
(‘$reid’,’$topid’,’$sortrank’,’$typename’,’$typedir’,’$typeimg’,
保存catalog_add.php
下面修改catalog_edit.php文件
打开dede/catalog_edit.php
查找$upquery = “Update `dede_arctype` set
在 typedir=’$typedir’, 其下面增加一行：
`typeimg`=’$typeimg’,
保存catalog_edit.php
开始修改栏目添加模板文件
打开dede/templets/catalog_add.htm
在最上面找到这个段

保存catalog_edit.htm
至此已经修改完成!
栏目图片的添加或修改图片时在 (栏目管理>高级选项)里面就会自动出现栏目图片添加的选择，点击选择图片，弹出窗口内选择浏览上传就OK
注意：前台栏目标签调用的时候，还需要改一个文件，才能实现栏目图片显示，否则只能通过sql语句才能显示图片。
打开：include/taglib/channel.lib.php
找到
if($type==’top’) { $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row”; } else if($type==”son”) { //if($_sys_globals[‘typeid’]>0) $typeid = $_sys_globals[‘typeid’]; if($typeid==0) { return ”; } $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=’$typeid’ And ishidden<>1 order by sortrank asc limit 0,$row”; } else if($type==”self”) { if($reid==0) { return ”; } $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=’$reid’ And ishidden<>1 order by sortrank asc limit 0,$row”; }
替换成下面的：
if($type==’top’) { $sql = “Select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row”; } else if($type==”son”) { //if($_sys_globals[‘typeid’]>0) $typeid = $_sys_globals[‘typeid’]; if($typeid==0) { return ”; } $sql = “Select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=’$typeid’ And ishidden<>1 order by sortrank asc limit 0,$row”; } else if($type==”self”) { if($reid==0) { return ”; } $sql = “Select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid=’$reid’ And ishidden<>1 order by sortrank asc limit 0,$row”; }
调用方法：
<img src=”[field:typeimg /]” />
如果想同时在文章内容页调用栏目图片打开，修改\include\arc.archives.class.php
查找
if($this->ChannelUnit->ChannelInfos[‘issystem’]!=-1)
将
$query = “Select arc.*,tp.reid,tp.typedir,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$aid’ “; $this->Fields = $this->dsql->GetOne($query);
替换为：
$query = “Select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable from `dede_archives` arc left join dede_arctype tp on tp.id=arc.typeid left join dede_channeltype as ch on arc.channel = ch.id where arc.id=’$aid’ “; $this->Fields = $this->dsql->GetOne($query);
保存文件即可。
